Microsoft distributes Microsoft SQL Server 2008 fixes as one downloadable file. Because the fixes are cumulative, each new release contains all the hotfixes and all the security fixes that were included with the previous SQL Server 2008 fix release.

SYMPTOMS

You create or edit a Microsoft SQL Server 2008 Integration Services (SSIS) package in Business Intelligence Development Studio (BIDS). You edit an OLE DB source in a Data Flow task. When you click the Columns tab, you receive the following error message:

Note The DTS_E_OLEDBERROR error code has many causes. This article describes only one rare problem that has a specific cause. To make sure that you are encountering this problem, see the "More Information" section for a troubleshooting method.

Note This problem does not occur in SQL Server 2005.

CAUSE

In SQL Server 2008 SSIS, a specific check determines whether the identifiers that are used by an OLE DB provider are case-sensitive. This check allows for SSIS to follow the case-sensitivity that is defined by an OLE DB provider configuration when SSIS lists object names, table names, and column names. This check is performed by implementing an OLE DB property that is named DBPROP_IDENTIFIERCASE. However, not all OLE DB providers support and implement this property. If the property is not implemented, an error may occur in the BIDS.

RESOLUTION

Cumulative update information

SQL Server 2008 Service Pack 1

Important You must install this cumulative update package if your computer is running SQL Server 2008 Service Pack 1.

The fix for this issue was also later released in Cumulative Update 3 for SQL Server 2008 Service Pack 1. For more information about this cumulative update package, click the following article number to view the article in the Microsoft Knowledge Base:

Note Because the builds are cumulative, each new fix release contains all the hotfixes and all the security fixes that were included with the previous SQL Server 2008 fix release.

Microsoft SQL Server 2008 hotfixes are created for specific SQL Server service packs. You must apply a SQL Server 2008 Service Pack 1 hotfix to an installation of SQL Server 2008 Service Pack 1. By default, any hotfix that is provided in a SQL Server service pack is included in the next SQL Server service pack.

This hotfix changes the behavior of the OLE DB source in SSIS to request the DBPROP_IDENTIFIERCASE property. After you apply this fix, SSIS ignores the failure of the DBPROP_IDENTIFIERCASE property. Instead, SSIS uses a default value for the identifiers. After you apply this hotfix, if the OLE DB provider does not implement the property, the identifiers are case-sensitive by default.

STATUS

Microsoft has confirmed that this is a problem in the Microsoft products that are listed in the "Applies to" section.

MORE INFORMATION

Troubleshooting

To make sure that you are encountering this problem, follow these steps:

Select the provider, the source, the login, and the other connection string attributes. Then, click OK.

After the connection is successfully completed, on the DataSource menu, point to IDBPProperties, and then click GetProperties.

In the PropSet list, select DBPROPSET_DATASOURCEINFO.

If the DBPROP_IDENTIFIERCASE property is not listed as an available property, or if the DBPROP_IDENTIFIERCASE property has a green question mark next to the property, the provider does not support this property. In this situation, you will encounter the problem that the "Symptoms" section describes.

Steps to reproduce the problem

In SQL Server 2008 BIDS, create a new SSIS package.

Add a Data Flow task to the package.

Add an OLE DB Source component in the Data Flow task.

Configure Connection Manager to use an OLE DB provider that does not support the DBPROP_IDENTIFIERCASE property.

Select a table, a view, or a SQL command, and then provide the required object name or SQL command.

In the left pane, click the Columns tab.

You receive the error message that the "Symptoms" section describes.
